  • Publication number: 20100080915
    Abstract: When a position of a film formation mask is recognized by irradiating the film formation mask with light, an image having a high contrast cannot be obtained, which unstabilizes reproducibility of measurement accuracy for an alignment mark position, leading to an alignment error between a substrate and a mask. Provided is a film formation mask including a mask sheet having a positioning opening and a mask frame, in which a reflective member having a reflectance higher than that of the mask sheet is provided to the positioning opening. When light is irradiated onto the positioning opening of the film formation mask, an intensity difference between light reflected by the mask sheet and light reflected by the reflective member becomes stable. Therefore, the position of the film formation mask may be determined with high reproducibility.
